    Hey i recently bought a dt125x and I need to replace the fork seals but can't find any information about the real size, many forums and sites have different mesurements so I figured the easiest would be to ask here

    I have tried another CDI still no luck. No servo cycle and no spark. I have tried three different stators and same result. Because the replacement bits I .trying are second hand I have now way of knowing if they are ok. Is there a way to work through the bots one by one. For example can I connect the servo to the battery somehow to see if it works? I can turn it by hand so it's not seized. I don't understand why servo and coil not working. Please help.

    Well are you sure it's beyond repair? I mean it has to be pretty bad for that to be the case?

    I’ve tried another cap ( an old one that came with the bike as the bike came with 2 boxes of parts) and it seams to be worse so I think that shows both caps are bad and the og one wasn’t as bad Thank you very much

    You guys have given me a lot to work with... No, I definitely won't be riding it anywhere when it's running like this. I'll print off this whole thread and show it to my friend who knows a lot more about bikes than me... Thanks

    @irongamer727 You probably won't gain higher revs, as unfortunately, the ability to rev higher is lost with the bigger bore. But yes, you will be able to dial in the ignition much more towards the bigger cylinder. I'd have thought there would be some nice gains with this and the bigger bore.

    @perithtv I've been there too few months ago. Soaking , heating etc etc nothing Take off everything possible what can restrict you in the back and chop the bolt on as much places as angle grinder let you. I had 4 cuts and lifted the pieces off. Bought brand new guts for it and there is more grease then metal on it damaged my axe on it too

    When I bought my bike carb was leaking from overflow pipe all the time, when tank valve was open. I opened the carb and the reason was that, the float valve was upside down! I turn it to right way and overflow stop immediately!!! Check that!

    Cant see why you wouldt want to get better filtration... Airfilter oil is pretty cheap, and the filter is made to flow this way. Youd' be surprised how much crap it catches when you clean it.

    @Mightyman Nah the DTRE's were given full YPVS servos. Although you make a good point, the YPVS does shut off at 10'000 rpm as a restriction. But the point here is the build up of NoX's gases. So whilst they did shut off, the normal person would be part throttle anyway. And if you were pinning it, well you would expect it to give up eventually and this might be why.
